DISK CULTIVATOR.

Specification of Letters Patent.

Patented March 9, 1909.

To all whom it may concern:

Be it known that we, Josnrn S. BUKAOEK and Josnrn O. Hummus, citizens ofthe United States, residing at Riverside, in the county of St. Clair andState of Alabama, have invented a new and useful Disk Cultivator, ofwhich the following is a specifica tion.

The invention relates to improvements in disk cultivators.

The object of the present invention is to improve the construction ofdisk cultivators, and to provide a simple, inexpensive and efficientdisk cultivator, adapted to be drawn by a single horse, and designedparticularly for cultivating small or stumpy fields, where a two horsedisk cultivator is practically useless.

A further object of the invention is to provide a disk cultivator ofthis character, adapted to be advantageously employed on extensivefarms, and capable of operating between the rows of plants, when thelatter are too tail to admit of the soil being cultivated by a two horsestraddle row cultivator.

Another object of the invention is to provide a disk cultivator of thischaracter having spaced gangs of disks capable of lateral and pivotaladjustment, to space the gangs the desired distance apart, and toarrange the disks for throwing the soil either toward or from the centerof the cultivator.

The invention also has for its object to provide means for preventingyoung plants from being covered up by the soil, when the disks are setto throw the soil toward the plants.

With these and other objects in view, the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawings, and pointed out in the claimhereto appended; it being understood that various changes in the form,proportion, size and minor details of construction, within the scope ofthe claim, may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

In the drawings :Figure 1 is a erspective view of a single horse disk ontivator, constructed in accordance with this invention, the disks beingarranged to throw the soil inwardly, and the fender being in positionfor preventing the plants from being covered. Fig. 2 is a plan view ofthe same. Fig. 3 is a transverse sectional view of one of the gangs ofdisks. Fig. 4 is a sectional view on the line -00 of Fig. 2,illustrating the manner of attaching the fender to the beam. Fig. 5 is alongitudinal sectional view, the fender being removed and a tooth beingattached to the rear end of the beam for cutting down the hill betweenthe inner disks of the gangs.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

The single horse cultivator, while being particularly adapted forcultivating stumpy ground and for use in fields having short rows, maybe advantageously employed on extensive farms, and it embodies two gangsof cultivating disks 1, spaced apart and located at opposite sides of abeam 2, which is provided at its front end with a suitable clevis 8 forthe attachment of the draft animal. The disks are of the usualconcavoconvex form and those of each gang are mounted on a shaft or axle4., which is journaled at its ends 5 and 6 in suitable bearings 7 and 8of an arch 9. The shaft is square in cross section and the disks are saced apart by means of sleeves 10, provided with rectangular bores oropenings to conform to the configuration of the shaft or axle 4, and thelatter is threaded at the terminals of the squared portion to receivenuts 11. The inner bearing 8 consists of a circular bearing opening,through which the journal 6 extends, and the outer bearing 7 consists ofa recess, extending upwardly from the lower end of the outer side of thearch, the journal 5 being retained in the recess by a key 12, or othersuitable fastening device, but the axle or shaft may be detachablymounted on the sides of the arch, as will be readily understood.

The arches have horizontal top connecting portions, which are providedwith suitable perforations 13 for the reception of bolts 14, or othersuitable fastening devices for pivotally connecting the arches to atransverse bar 15, having similar perforations 16 and centrally securedto the lower face of the beams 2. The beam is preferably provided in itslower face with a transverse recess 17 for the reception of the bar 15,which is fastened to the beam by a bolt 18, or other suitable fasteningdevice. The bar 15 forms a pair of laterally projecting arms, to whichthe said arches are adjustably pivoted. The arches are adapted to beturned on the pivots 14- to arrange them at the desired angle, and thedetachable shaft or axle enables the disks to be arranged with theirconcave faces either toward or from the beam for throwing the soileither inwardly or outwardly.

The arches are secured in their pivotal adjustment by means of curvedbraces 19 and 19, consisting of a substantially semicircular b'ar ormember, permanently pivoted by a bolt 20, or other suitable fasteningdevice to the lower face of the beam at a point in advance of the gangsof disks, and extending rearwardly at each side of the beam. The rearportions of the braces 19 and 19 are provided at intervals withperforations 21 for the reception of bolts 22., which pierce the archesand secure the latter in their pivotal adjustment. Any other suitablemeans, however, may be employed for adjustably connecting the arches tothe arcuate brace 19 and 19.

hen the outer portions of the arches are swung backwardly to points inrear of the transverse bar or member 15, and the disks are arranged tothrow the soil toward the center of the cultivator, a fender 23'isarranged between the two gangs of disks to prevent young plants frombeing covered up by the soil. pair of longitudinal sides or blades 24,ar ranged in vertical planes and connected by front and rear arclies 25and 26. Tlce arc! es .arese'cured to the rear portion of an inclinedresilient standard or member 27, which extends upwardly and forwardlyfrom tie front arch 25 to the face of the front portion of the beam 2.The upper front end of t e resilient standard or member 27 is secured tothe beam 2 by a bolt 28, or other suitable fastening device, and it isl;eld against lateral oscillation by a substantially U-slzaped stirrupor clip 29, composed of spaced sides and a transverse connectingportion, which is provided with. a groove 30 to receive the standard ormember 27. The sides of tie stirrup or clip 29 aresecured to the beam bya transverse fastening device 31. Tlie fender is detachably connectedwith. the beam, and when it is desired to use the fender, tle standard27 is passed through the clip or stirrup 29, and is secured by the bolt28. The sides or blades of the fender are in the form of runners, theirlower front corners being cut away and rounded, as shown, and theresilient standard 27 permits the fender to spring upward and downwardin passing over obstructions, the disks being adapted to roll The fenderis composed of a over the same without jarring the cultivator or thedriver.

When the fender is not employed and the cultivator is used as a barrow,a spring tooth 32 is attached to the rear end of the beam to cut downthe hill between the inner disks of the gangs. The spring tooth, whichmay be of any preferred construction, is secured to the beam by a singlebolt 33, a stirrup or clip 34 being secured to the beam in rear of thebolt and 1 reventing the spring tooth from swinging laterally on thebolt 33. T5 e stirrup or clip, which is approximately U- shaped, issecured to the beam by a transverse bolt 35, as clearly illustrated inFig. 5 of the drawings. Tie beam is equipped with plow handles 36-of theordinary construction, secured at their lower end to the opposite facesof the rear portion of the beam. and connected near their upper end by atransverse rung.

This cultivator besides being lighter and less expensive than a twohorse cultivator, also possesses the advantage of being able tocultivate the soil between rows of plants, wli en tlze latter are toohigh to admit of tlxe use of a straddle row cultivator.

Having thus fully described our invention, what we claim as new anddesire to secure by Lete-rs Patent, is

In a cultivator, til e combination of a longitudinal beam having fixedlaterally extending arms provided at intervals with perforations, spacedgangs of cultivating devices provided with arcfll. es pivoted to thelaterally extending arms and projecting beyond ti e outer ends of tllearms, t iie pivots of tile arcl; es being adapted to be arranged in tesaid perforations to enable the arei. es to be adjusted along tl1e armsin a direction transversely of the beam, and forwardlyextendingconverging braces permanently ivoted to tie beam in advance of t .elatera ly extending arms and adjustably connected at points beyond tlieouter ends of the latter to the said arches and securing the same intheir pivotal adjustment, said braces being independ- 'ently adjustableand movable inwardly and outwardly with the arches in their adjust menttransversely of the beam.

In testimony, tlt at we claim the foregoing as our own, we is ave heretoaffixed our signatures in the presence of two witnesses.
